Awake Time not working

My WHOOP keeps showing that I’m awake for over an hour every night, even though I don’t remember waking up at all.

To compare, I wore another sleep tracker at the same time. That watch separates restless sleep from awake time, and it showed only about 15 minutes awake. WHOOP doesn’t seem to have a restless sleep category, so I’m wondering if it’s counting restless sleep as awake instead.

I’ve also seen a lot of other people on Reddit mentioning the same issue with WHOOP overestimating awake time.

Has anyone found a fix, or is this just how WHOOP tracks sleep?
